What is the Sliding Filament Theory?

A

The sliding filament theory is the explanation for how muscles produce force (or, usually, shorten). It explains that the thick and thin filaments within the sarcomere slide past one another, shortening the entire length of the sarcomere.

Functions of spleen

A

The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.

Q

What are lymphatic capillaries

A

Lymph capillaries or lymphatic capillaries are tiny, thin-walled vessels located in the spaces between cells (except in the central nervous system and non-vascular tissues) which serve to drain and process extra-cellular fluid.

Q

What occurs when someone has heart disease?

A

The heart can’t pump enough blood to fill the body’s needs.

42
Q

What happens when the diaphragm contracts

A

You inhale and your lungs open up

43
Q

Where does oxygen enter the blood stream?

A

Diffusion of the alveoli.

44
Q

Where does the trachea lead?

A

Bronchi

45
Q

Why is your left lung smaller?

A

The right holds 2/3 of the heart

46
Q

Functions of epiglottis

A

The epiglottis is a flexible flap at the superior end of the larynx in the throat. It acts as a switch between the larynx and the esophagus to permit air to enter the airway to the lungs and food to pass into the gastrointestinal tract. The epiglottis also protects the body from choking on food that would normally obstruct the airway.

47
Q

Where is the medulla oblongata located?

A

In the brain stem

48
Q

What is the space between one neuron’s dendrites and another neuron’s axon terminals?

A

Synapses

49
Q

Which of the following is NOT a division of the Peripheral nervous system?

A

Spinal Cord brain

50
Q

The______________ system controls the fight-or-flight response.

A

Autonomic Nervous System

51
Q

What is the difference between the positive and negative feedback loops

A

Negative feedback keeps things under control and positive feedback makes things out of control

52
Q

What is the difference between endocrine and exocrine organs.

A

Endocrine glands secrete hormones, which are chemical “messengers” that travel through the blood to regulate the activity of a target organ. Glands that have ducts are called exocrine glands. The secretions of exocrine glands reach their target by traveling through a duct (tube).

53
Q

What is the master gland and its function.

A

The pituitary gland is often dubbed the “master gland” because its hormones control other parts of the endocrine system, namely the thyroid gland, adrenal glands, ovaries, and testes. However, the pituitary doesn’t entirely run the show.

54
Q

What is the function of the endocrine system.

A

The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body’s growth, metabolism (the physical and chemical processes of the body), and sexual development and function.

55
Q

How do hormones travel through the body?

A

Hormones travel throughout the body, either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell’s activities.

56
Q

Types of Endocrine glands

A

Thyroid, pituitary, adrenal

57
Q

_______ are a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action

A

Hormones

58
Q

What gland secretes insulin?

A

Functioning as a Exocrine gland, pancreas

59
Q

The thymus gland is responsible for…?

A

The thymus gland, despite containing glandular tissue and producing several hormones, is much more closely associated with the immune system than with the endocrine system. The thymus serves a vital role in the training and development of T-lymphocytes or T cells, an extremely important type of white blood cell.

60
Q

What organs produce liquid to help carry sperm

A

Semen, seminal vesicles

61
Q

What does the liver make?

62
Q

What substance enters the small intestine after stomach digestion?

A

The gallbladder

65
Q

68
Q

What other body system is the pharynx a part of?

A

Digestive and respiratory

69
Q

Functions of Pepsin

A

Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides. It was discovered in 1836 by Theodor Schwann who also coined its name from the Greek word πέψις pepsis, meaning “digestion” (from πέπτειν peptein “to digest”).

70
Q

What are the main structures of a nephron?

A

Arcuate artery and vein

71
Q

What is the difference between the renal artery and the renal vein?

A

Renal artery carries oxygenated blood containing high levels of urea to the kidneys for filtration.

Renal vein carries dexygenated blood which has had urea removed away from the kidneys.

72
Q

What order does urine go through in the excretory system?

A

The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination. Besides filtering and eliminating wastes from the body, the urinary system also maintains the homeostasis of water, ions, pH, blood pressure, calcium and red blood cells

73
Q

What is dialysis?

A

the clinical purification of blood by dialysis, as a substitute for the normal function of the kidney.

74
Q
