<u>Answer</u>: Ionic bond
<u>Explanation</u>:
- An ionic bond is a type of a chemical bond formed by the complete transfer of electrons from one atom to another atom i.e one of the atoms loses its electrons and the other gains it. This results in the formation of 2 oppositely charged ions.
- In sodium chloride, sodium loses one electron from its outermost shell (valence shell) whereas chloride gains it. Due to this sodium gains, a net positive charge and chloride gain a net negative charge.
- So, due to the complete transfer of electrons that takes place from sodium to chloride, the compound generated (Sodium chloride) has an ionic bond.

Answer:
Capillary beds: Capillary beds are the site of nutrient and oxygen delivery to tissues.
Explanation:
Capillary beds are part of a bigger system in the human body: circulatory system, whicis also called vascular or cardiovascular system. It is connected with other systems such as the respiratory and the excretory system.
Capillary beds <em>don't have a total cross-sectional area much smaller than the total cross-sectional area of major arterie and they don't join of arteries and veins. </em>Actually, the capillaries are the ones that connect arteries and veins.
Capillary beds are the site of nutrient and oxygen delivery to tissues. A capillary bed is a network full of capillaries. In this space there is a fluid exchange. And the more metabolic activity a cell has, the more capillaries are needed for a right and sufficient supply.
