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:
Loop of Henle lenght
Explanation:
Juxtamedullary nephrons have a longer loop of Henle that cortical nephrons and as we know this loop has a great function reabsorving water, the longer it is more water is reabsorved. The descending portion of the loop is permeable to ions but not to water so this portion reaborves a great quantity of water. Then in the ascending loop is the opposite, it is permeable to water but not to ions. The ions reabsorved in the ascending loop (20-25% of the Na+) are responsable of the water reabsorved in the descending loop. The longer the loop is more water and ions are reabsorved.
