B, AB, and O blood groups are distinguished by:

Malfunction of the nervous system

Complete paralysis is usually due to:

Ligaments

Connective tissue which holds bones together at the joints:

Urine

Found in the kidney pelvis

The reason is nearsighted

Myopia is an eye condition in which:

Eustachian tube

Pressure is equalized on both sides of the tympanic membrane of the ear through a structure called the _______________________________.

Seminiferous tubules

Sperm cells are produced within the testes in structures called:

Cerebrum

The ___________________ is the portion of the brain involved in sensory perception

Medulla

The actions of internal organs are regulated by the part of the brain called the __________________.

Sympathetic

The activity of digestive organs is slowed down by a series of ganglia and nerves in each side of the spinal column called the ______________________ system. This system stimulates the heart rate and the "fight or flight" response.

Fovea

The area of the eye with a concentration of cones is the:

70

The average heart rate value for a healthy adult is __________ beats/min.

The veins leaving the heart, the aorta, the arteries carrying blood to the body

The blood vessels that carry oxygenated blood are:

Small intestine

The breakdown of food into molecules small enough to enter the blood stream is primarily accomplished in the:

Platelets

The cellular component of the blood that is important in the blood clotting mechanism is called _________________________.

Leukocytes, erythrocytes

The cellular component of the blood that is involved in the body's defenses is called ________________________, and the cellular component that contains hemoglobin is called __________________________.

Rh factor

The clotting of blood includes all of the following materials except:

ATP

The energy needed for muscle contraction comes directly from:

Sclera, cornea, choroid, retina, pupil, iris, lens

The eye has many structures built into it which enable us to see. It is composed of three layers. The outermost layer, composed of a fibrous material, is called the ______________. This layer stretches around the front of the eye and becomes transparent. At this point it is called the _______________. The middle layer, the _________________, is made of a darkly pigmented tissue. The third or inner layer is responsible for the reception of the light rays and the translation of that stimulus into an impulse for the optic nerve, which takes it to the brain for interpretation of the image. This light-sensitive layer is called the ______________. Light enters the eye via a circular opening called the _________________. This eye part can be opened or constricted by a special colored part of the middle eye layer called the ________________, which acts much as the shutter on a camera works. The light is focused on to the light-sensitive inner layer by the ______________, which can be changed in shape by the ciliary muscle.

Produce urine by filtering blood

The function of the nephron is to:

Nerve

The funny bone is a:

The pelvic girdle is also referred to as the ______________ and consists of __________ sections.

Insertion, origin

The point where the muscle attaches to the more movable bone in a joint is referred to as the ___________________, and the point where the muscle attaches to the less movable bone in a joint is called the _________________.
