Which organ is the site of gas exchange?
Answers
Answer:
lungs
Explanation:
lungs
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The lungs exchange gases

(A) carry oxygen
(B) act as a buffer
(C) bind with hemoglobin
(D) supply cells with carbon
(E) increase the rate of cellular respiration
Answers
Bicarbonate ions present in body performs a variety of functions, in blood it carries carbon dioxide. Its other functions include keeping the balance of acids and bases in the body. It acts as a buffer.
What is a buffer?Buffer is a type of solution that resists pH change either by the addition of acid or base.
Bicarbonate is a base, which the body requires to keep a normal acid-base (pH) balance.
This balance prevents the body from having too much acid means maintaining buffer. The lungs and kidneys helps to keep a normal blood pH by removing excess acid.
Thus, the correct option is B.

what is inside your capillaries that carries oxygen to your heart?
Answers
Answer:
Capillaries are narrow blood vessels. Blood contains plasma, red blood cells, white blood cells and platelets. Red Blood cells are bi-concave disc which contains hemoglobin that reacts with oxygen and thus oxygen is transported by RBC to the heart where it is distributed to the whole body
Veins are present inside your capillaries that carry oxygen to your heart. While arteries perform the opposite function which carries blood away from the heart.
What are the functions of capillaries?The functions of capillaries are as follows:
Capillaries transport blood, oxygen, and nutrients to every cell. They are the type of delicate blood vessels that exist throughout your body. They also exchange waste throughout the body.Capillaries also help in the connection of arteries and veins.Capillaries are the connection link of both arteries and veins. So, both arteries and veins perform their specific function in order to facilitate the transport of deoxygenated blood and oxygenated blood to and from the heart respectively.
Therefore, the structure inside your capillaries that carries oxygen to your heart is known as veins.

3. How might you be able to tell that enzymes are working in your body?
4. How do different types of food change the number of digestive enzymes present in your body?
Answers
Answer:
1. Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.
2.The SmartPill is an ingested, wireless device for measuring the health of the digestive system. As it passes through the digestive tract, the capsule transmits data to a receiver, which is later returned to the doctor and the information downloaded onto a laptop computer.
3. When its not working many of the uncomfortable reactions such as an upset stomach, allergy-like symptoms or irritability are actually signs that the enzymes are working. The body is cleaning itself out and the healing process is starting.

Nutrients Nutrients are substances in food that supply the body with energy and raw materials needed for growth, repair, and mainteNnce. The nutrients that the body needs are water, carbohydrates, fats, proteins, vitamins, and minerals.
- Many of the body's processes take place in water. Water makes up a large part of blood and other body fluids.
- Simple and complex carbohydrates are the body's main source of energy. Complex carbohydrates, such as starches, must be broken down into simple sugars to be used for energy.
- Fats are formed from fatty acids and glycerol. Fats help the body absorb fat-soluble vitamins and are a part of cell membranes, nerve cells, and certain hormones.
- Proteins supply raw materials for growth and repair of structures such as skin and muscle. Many enzymes and hormones are proteins.
- Vitamins are organic molecules that the body needs in very small amounts. They are needed to help the body perform chemical reactions.
- Minerals are inorganic nutrients the body needs in small amounts. Examples of minerals include calcium and iron.
