Breathing In (Inhalation)
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli (air sacs).
Through the very thin walls of the alveoli, oxygen from the air passes to the surrounding capillaries (blood vessels). A red blood cell protein called hemoglobin (HEE-muh-glow-bin) helps move oxygen from the air sacs to the blood.
At the same time, carbon dioxide moves from the capillaries into the air sacs. The gas has traveled in the bloodstream from the right side of the heart through the pulmonary artery.
Oxygen-rich blood from the lungs is carried through a network of capillaries to the pulmonary vein. This vein delivers the oxygen-rich blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding tissues.

Breathing Out (Exhalation)
When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity. When you're physically active, your abdominal muscles contract and push your diaphragm against your lungs even more than usual. This rapidly pushes air out of your lungs.

What is the bloodstream in the human body?</h3>
Blood running through an organism's body is referred to as the bloodstream.
In humans, the circulatory system, which is made up of a complicated network of arteries and veins, is where blood travels.
- Transporting nutrients and oxygen to the tissues and lungs is one of the bloodstream's functions.
- Waste carbon dioxide from the cells is removed by the bloodstream.

Answer:
the options does not tally with the question. Below is what i suggest it should be.
Explanation:
A patient with gastroesophageal reflux disease (GERD) is experiencing increasing discomfort. Which patient statement indicates that additional teaching about GERD is needed?

b.
"I sleep with the head of the bed elevated on 4-inch blocks."
c.
"I eat small meals during the day and have a bedtime snack."
d.
"I quit smoking several years ago, but I still chew a lot of gum.
Answer is C because GERD is aggravating by the patient eating late at night, the nurse should teach him or her to prevent eating at bedtime.

a.
"Peppermint tea may reduce your symptoms."
b.
"Keep the head of your bed elevated on blocks."
c.
"You should avoid eating between meals to reduce acid secretion."
d.
"Vigorous physical activities may increase the incidence of reflux."
Answer- B because Elevating the head of the bed will reduce the incidence of reflux.
