Answer: 1. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
2. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
3.Within the bone marrow, all blood cells originate from a single type of unspecialized cell called a stem cell. When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell.
4. Epinephrine and norepinephrine, hormones secreted by the adrenal medulla, raise blood pressure by increasing heart rate and the contractility of the heart muscles and by causing vasoconstriction of arteries and veins. These hormones are secreted as part of the fight‐or‐flight response.
Answer:
In this protein supplement there are 11 grams of protein which contribute with 44 kcalories. Therefore, the percentage of kcalories coming from protein in this particular supplement is 28,5 %.
Explanation:
Each gram of protein contributes 4 kcal (calories), so 11 grams of proteins x 4 kcal/gram = 44 kcal.
The total amount of kcalories is 154, so 44 kcal / 154 kcal x 100 = 28,5%.
When it comes to protein supplements is very important to realise how many proteins are being consumed and how many total calories this supplement has, for the simple reason that it might be not help to reach the protein goal for a particular individual, but instead, it might be providing too many calories that come from non-protein compounds.
Answer:

Cartilage is a tough, elastic connective tissue that helps to reduce friction between bones.
