Answer: Option C
Explanation:
The nephron is the microscopic structure found in the kidney. It is the structural and functional unit of kidney.
It is composed of renal tubule, glomerulus and Bowman's capsule. The renal corpuscles consists of a tuft of capillaries which is known as glomerulus.
Bowman's Capsule can be defined as a sac like structure that lies at the starting of the tubular part of a nephron in a kidney. It performs the first step of filtration of blood that reaches the kidney.
Hence, the correct answer is all of these.
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.
