A Texas teenager missed the start of his 11th grade year after he mysteriously fell ill.
Dominic Lopez’s family told Eyewitness News he’s been in the hospital since last Tuesday. He could barely tell his mother what was wrong.
“It was just a regular day. Thankfully, I work at home. He had just taken a shower. Shortly after that, he came to me in the kitchen. He was complaining of chest pain. He was holding his chest. He couldn’t really talk. He was taking really small breaths,” said his mother, Muriel Lopez. “Once I saw that, that he couldn’t really breathe properly … I put him in the truck because I knew I could get to the hospital faster than the ambulance could get to me.”
Muriel Lopez said in the four-minute drive to the hospital, she watched her son turn pale. She said doctors discovered her son’s left lung fully collapsed and diagnosed him with spontaneous pneumothorax. According to medical experts, tall and thin males teens are most susceptible.
Doctors put a tube in Dominic’s chest. He underwent surgery on Sunday.

“To me, I think getting this out there is the main thing. I’ve never heard of spontaneous pneumothorax before this. I had no idea that a young male who is tall and thin is more prone to get this condition,” said Dominic’s mom. “I have never heard of it. I was terrified. If you ever have any symptoms regarding your heart, chest, or your breathing … get to the nearest ER immediately.”

Because they are up there in my list of must do exercises for strong, defined and tight legs!
Lunges with heavy dumbbells, walking lunges, bodyweight, Bulgarians… so many variations and definitely credit these to changes I’ve seen in people’s lower body.
This is solely a lunge workout because I personally love how lunges help build muscle and definition in the legs and glutes, but aside from aesthetics they have so many benefits;
Lunges work the quads, hamstrings, glutes, and core!
They are a single leg movement so activation of stabiliser muscles lead to improved balance, stability and co-ordination.
Can help with any imbalances or misalignments you may have.
They can put less stress on spine so great option over squats if lower back issues. They also strengthen the core and back therefore helping decrease risk of injury in lower back in future.
The 10 exercises are performed for one minute then straight into the next exercise. This is follow along however just pause the movement when you need to!
The exercises are as follows:
Diagonal forward alternating lunge
Side to side
Reverse alternating
Lunge to rotational knee
Lunge to rotational knee
Forward alternating lunge w/ 2 pulses
Side lunge to curtsey
Side lunge to curtsey
Pulse lunges
Pulse lunges
The last 2 minutes is when the lactic acid really builds up and the burn rises! But push through it, you can do it!
Enjoy!

“Interstitial lung disease also known as diffuse parenchymal lung diseases (DPLDs) are a group of disorders based on similar clinical, radiographic, physiologic, and pathologic changes.
Present primarily with shortness of breath and a non productive cough usually chronic over weeks to months without response to initial treatment of puffers. If there is clinical suspicion of ILD a full pulmonary function test should be done. Characteristic changes of ILD include: reduced total lung capacity (TLC) and DLCO.
The diffuse parenchymal lung diseases are divided into those that are associated with known causes or unknown causes and other weird and wonderful rare causes.”

Deep-vein thrombosis (DVT) is a type of clot that forms in a major vein of the leg or, less commonly, in the arms, pelvis, or other large veins in the body. This video shows how in some cases, a clot in a vein may detach from its point of origin and travel through the heart to the lungs where it becomes wedged, preventing adequate blood flow. This is called a pulmonary (lung) embolism and can be extremely dangerous. To learn more about DVT and other blood disorders, visit ASH’s patient resources webpage http://hematology.org/Patients/.
This animation was featured in the documentary film “Blood Detectives.” To learn more about the film, visit http://www.hematology.org/Publications/Blood-Detectives/5246.aspx
DVTs and PEs. A deep vein thrombosis can lead to a pulmonary embolism. Both are bad, but what’s the anatomy that links these two things? We can also go over some terminology to make sure we understand the words, thrombus, embolism, and stuff.

The lungs are organs that allow you to breathe and are located in the thoracic cavity on either side of the heart and near the backbone. Their bases sit on the diaphragm, and their apexes extend into the root of the neck. The lungs perform gas exchange in microscopic alveoli, extracting oxygen from the air and transferring it to your bloodstream, while releasing carbon dioxide.
The respiratory system can be functionally divided into a conducting zone and a respiratory zone. The conducting zone forms a continuous passage for air moving in and out of the lungs, and includes the nose, pharynx, larynx, bronchi, and bronchioles. The respiratory zone is found deep in the lungs and is involved in gas exchange. This includes the respiratory bronchioles, alveolar ducts, and alveoli, which are air sacs 100-300 µm wide that allow gas exchange.
The respiratory system can also be divided anatomically into the upper and lower respiratory tracts. The upper respiratory tract consists of structures in the head and neck – in other words, the nose, pharynx, and larynx. The lower respiratory tract is located in the chest and includes the trachea, bronchi, bronchioles, alveolar ducts, and alveoli.
The lungs weigh around 1.3 kg and contain around two and a half thousand km of airways. The right lung is larger and heavier than the left, because the left needs to leave room for the heart. The right lung is subdivided into three lobes, while the left has two. However, the left lung has a structure homologous to the middle lobe of the right lung. On the left lung, the upper lobe has a projection called the “lingula”. The boundaries of these lobes are defined by fissures. The right lung has two fissures, one oblique and one horizontal. The left lung has only an oblique fissure.
The main, or primary, bronchi enter the lungs at the hilum, which is the area on the mediastinal surface of the lung through which structures enter and leave the lung. These primary bronchi branch into lobar, or secondary, bronchi, which supply air to each lobe of the lungs. The secondary bronchi then branch into segmental, or tertiary bronchi, which supply air to bronchopulmonary segments, which are subdivisions of the lobes. A bronchopulmonary segment has its own segmental bronchus and arterial supply.
The bronchi branch into bronchioles. The primary lobule, otherwise called the acinus, is the functional unit of the lung. It is composed of a single terminal bronchiole, numerous respiratory bronchioles, alveolar ducts, alveolar sacs, and around 10,000 alveoli. Pulmonary blood is delivered to it by a pulmonary arteriole and taken away by a pulmonary venule. The alveoli are where gas exchange takes place. Their 0.5-2 µm thick membranes form the blood-air barrier. Together, the 300-500 million alveoli in the lungs provide a huge surface area for gas exchange. Elastic fibers allow the alveoli to expand on inhalation. These spring back on exhalation to help expel carbon dioxide.
The lungs have a unique blood supply. They have two forms of circulation – pulmonary and bronchial. The pulmonary circulation brings deoxygenated blood from the body to the lungs via the pulmonary arteries and returns it via pulmonary veins. Meanwhile, the bronchial circulation provides oxygenated blood to the tissue of the lungs.
The lungs have very specific indentations from surrounding structures. The outer surface of the lungs faces the ribs, which make light indentations on them. The medial surfaces are even more interesting. We can see impressions of the heart, and the great vessels, which are the large vessels that bring blood to and from the heart.
The lungs can’t power the breathing process on their own, but only expand with the expansion of the thoracic cavity. Instead, muscles of respiration, primarily the diaphragm, drive breathing. The broad, concave base of the lungs sits on the convex surface of the diaphragm. The intercostal muscles pull the rib cage upwards. The respiratory muscles relax when you breath out. When you’ve breathed out, the volume of the air remaining in your lungs is called the functional residual capacity (FRC), which is around 2.5-3 L in an adult.
When you’re exercising, heavy breathing recruits accessory muscles in the neck and abdomen, pulling the ribcage down upon exhalation and further decreasing the volume of the thoracic cavity to around 1 L. The movement of the lungs encounters little friction thanks to the pleural sac. This sac also divides the lungs into lobes. The pleurae are two serous membranes, one lining the inner wall of the ribcage, and one resting on the surface of the lungs. Between these membranes is the pleural cavity, which contains pleural fluid for lubrication.
