Give one word for the following.
1. The thickest blood vessel.
2. A pigment that causes red colour of blood.
8. The universal recipient.
1. Pressure exerted by the blood against the wall of arteries.
6. Bead-like structures found in the lymph vessels.
Answers
Answer:
1)An artery is a blood vessel that conducts blood away from the heart. All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart. However, those close to the heart have the thickest walls, containing a high percentage of elastic fibers in all three of their tunics.
2)hemoglobin
Red blood cells: The blood cells that carry oxygen. Red cells contain hemoglobin and it is the hemoglobin which permits them to transport oxygen (and carbon dioxide). Hemoglobin, aside from being a transport molecule, is a pigment. It gives the cells their red color (and their name).
3)Blood pressure (BP) is the pressure exerted by blood on the walls of a blood vessel that helps to push blood through the body. Systolic blood pressure measures the amount of pressure that blood exerts on vessels while the heart is beating.
4)The lymph nodes, or lymph glands, are small, encapsulated bean-shaped structures composed of lymphatic... ... Lymph and its associated cells enter through the afferent lymphatic vessels, which drain into each node through its convex surface.

Answer:
2) Haemoglobin
8) Type AB-positive blood is called the "universal recipient" type because a person who has it can receive blood of any type.
