secretion and absorption found in kidney, ducts and surface ovary

Blood is what type of tissue

tissue type that cannot regenerate

found in linings and on surfaces of organs, ducts, tracts...

controls involuntary movement ... found in digestive tract

mineralized connective tissue exerts important functions in the body, such as locomotion, support and protection of soft tissues

central core of the body

consists of the bones of the appendages (arms and legs) and the girdles (shoulder and pelvic)

explanation for how muscles contract to produce force

thick filament that is a prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement.

thin filament responsible for many types of cell movements

these ions released into the muscle interior where they bind to troponin, thus causing tropomyosin to shift from the face of the actin filament to which myosin heads need to bind to produce contraction

attached to the protein tropomyosin and lies within the groove between actin filaments in muscle tissue

In a relaxed muscle, blocks the attachment site for the myosin crossbridge, thus preventing contraction

chemical synapse formed by the contact between a motor neuron and a muscle fiber and able to transmit a signal to the muscle fiber, causing muscle contraction.

Each fiber is a single cylindrical cell. may be made up of hundreds, or even thousands, of fibers bundled together and wrapped in a connective tissue covering. Each is surrounded by a connective tissue sheath called the epimysium. Sarcolemma, actin, mysin are bundled

controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement

consists of the nerves and ganglia outside the brain and spinal cord

the three membranes (the dura mater, arachnoid, and pia mater) that line the skull and vertebral canal and enclose the brain and spinal cord.

each of the paired lobes of the brain lying immediately behind the forehead, including areas concerned with behavior, learning, personality, and voluntary movement.

either of the paired lobes of the brain at the top of the head, including areas concerned with the reception and correlation of sensory information.

coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.

A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.

Capillary blood contains low levels of Ca++ concentration which stimulates secretion of parathyroid hormone PTH

electric signals that pass from one end of the cell to another and release chemical messengers called neurotransmitters to communicate with other cells.

Promotes normal development

Targets skeletal muscle and bones

stimulates gamete production

Stimulates uterine contractions

Which of the following is not a formed element of blood

the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended.

also called erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O₂) to the body tissues

also called leukocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders

aid in clotting

process which causes bleeding to stop, meaning to keep blood within a damaged blood vessel

Which of the followng is the correct order of hemostasis?

high blood pressure

Not a cause of hypertension

hardening of the arteries

Which of the following factors does not affect blood flow

moving air into and out of the lungs

Exchanging gases between the air in the lungs and the blood

Exchanging gas between the blood and the body cells

Where gas exchange occurs in the lungs

Not a Factor affecting respiration

The absorption of nutrients occurs in which structure

digestion that includes the breaking down of food into smaller pieces

Chyme is made to help breakdown food so it can be absorbed

Carries urine from the kidney to the bladder

carries urine from the bladder outside

the part of the nervous system responsible for control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes

activates what is often termed the fight or flight response.

controls homeostasis and the body at rest and is responsible for the body's "rest and digest" function

the hearing organ

maintains balance

path light enters the eye : True or False:

cornea, aqueous humor, pupil, lens, vitreous humor, retina, optic nerve, brain

initial immune reaction against foreign antigens via nonspecific antibodies and immune cells.

involves the activation of T helper lymphocytes that recognize unique antigens

Infection; contact with pathogen

vaccine; dead or attenuated pathogens

Antibodies passed from mother to fetus via placenta; or to infant in her milk

What type of infections do antibiotics work on?

Lymph nodes

how is lymph propelled throughout the body

takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products.

takes place without the use of oxygen, produces small amounts of energy. Alcohol or lactic acid or other compounds are produced as waste products depending on the kind of cells that are active

Involves ATP

macromolecule made up of carbon, hydrogen and oxygen

fast source of energy and body's preferred energy method- used in cellular respiration quickly

Having a common method allows scientists to repeat other work creating validity in the science world.
