Intro to A & P

Study Slideshow

What does hydrophilic mean and what does it refer to?

Water-loving, It refers to the phosphate end of a phospholipid

15

What is Chromatin?

disorganized DNA

15

What is histology?

The study of tissues

15

What is selective permeability?

The ability to let certain materials in or out while restricting others

15

What is Physiology?

The study of how the parts of an organism work and how they work together

15

What is homeostasis?

A state of dynamic equilibrium in the body with respect to its internal environment and functions

15

What do we call something that can threaten homeostasis?

a stress

15

Name 2 stresses and what the body does about it.

temperature:sweating or shivering, blood sugar(candybar): high-insulin low-liver puts out glucose, BP: high-slow heart rate, low-increase heart rate

15

What are the greek roots and their meanings for homeostasis

homeo-same, stasis-standing

15

Is this a positive or negative feedback system? What is the control center? What is the effector?

negative feedback system, control center- sympathetic nervous system, Effector-heart or muscles around the blood vessels

25

Describe and give an example of a negative feedback system and a positive feedback system

negative- temperature, blood pressure, blood sugar positive-labor

25

Why does the plasma membrane reorient itself?

The phospholipids. The lipid tails are attracted to each other and the phosphate ends are attracted to the polar molecules of water,both inside&outside the cell

25

What are two ways large molecules brought into the cell?

Pinocytosis(very large such as proteins) and carrier proteins (large such as carbohydrates)

25

Give an example of passive transport

water and Na+ traveling through channel proteins from high to low concentration.Lipids which are non polar can pass right through the lipid membrane

15

What is active transport?

When something requires energy to move into the cell.

15

What do glycoproteins do?

The act as markers to identify the cells to recognize each other, ie: foreign cells, or as receptors to receive messages
