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.

<h3>What is
information?</h3>
Information is an amorphous concept that refers to things with the ability to inform. At its most basic, information refers to the interpretation of what can be sensed.
Facts and text features such as a table of contents, pictures, captions, bold print, and a glossary are examples of informational text characteristics. These characteristics assist the reader in finding information, supplementing information presented in text, drawing the reader's attention to key words, and explaining what words mean.
Definition speeches, demonstration speeches, explanatory speeches, and descriptive speeches are the four types of informative speeches. A definition speech explains the meaning, theory, or philosophy of a specific topic about which the audience is likely to be unfamiliar.
