Answer:
The given blanks can be filled with white pulp and red pulp.
Explanation:
In the lymphatic system, the spleen is considered as the largest organ. It is situated in the upper left part of the abdominal cavity, the main function of the spleen is to filter blood containing the destructed cells, pathogens like viruses and bacteria, and cellular debris.
The spleen generates and develops the mature immune cells, which possess the tendency of finding and eliminating the pathogens. The white pulp of the spleen comprises the immune cells, that is, the B and T lymphocytes, which help in fighting against the pathogens.
On the other hand, the red pulp of the spleen comprises connective tissue called the cords of Billroth, and various splenic sinusoids, which are filled with blood, providing it a red appearance. Its main function is to filter the blood containing microbes, pathogens, and worn-out or the defective RBCs.

Answer:Evaporation Evaporation is simply the process by which liquid turns into a gas. Water (a liquid) turns into vapor (a gas) when heat energy is applied to raise its temperature to 100°C (212°F). Water in the liquid state is a compound, and the heat breaks up the bonds into water molecules, which is gaseous.
Explanation:
<h2>a,d,b,c is the correct order</h2>
Explanation:
Before oxygen is picked up in the lungs by hemoglobin, it first diffuses through (a) alveolar cells,d) capillary walls (b) blood plasma, (c) red blood cell plasma membranes
- Although oxygen dissolves in blood, only a small amount of oxygen is transported this way,1.5 percent of oxygen in the blood is dissolved directly into the blood itself and most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues
- Hemoglobin (Hb) is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits
- Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules
- Molecules with more oxygen bound to the heme groups are brighter red because of which oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red
- At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out
- Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body
- Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava
- Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide
