question
Which of the following is true regarding the anatomical position? the feet are placed at exactly 45 degrees outward it is a visual reference point only used in the various imaging techniques the person is seated with head facing forward directional terminology refers to the body in this position the palms face posteriorly with the thumbs pointed toward the body
answer
directional terminology refers to the body in this position
question
Oxygen and hydrogen combine with one another to form water; this is an example of the ___ of organization
answer
chemical level
question
When many molecules come together to form organelles that become compartmentalized into a single structure that works as a unit, you have an example of the ____
answer
cellular level
question
Muscle fibers are cells that contain actin, myosin, and other accessory proteins. When these cells are collected together, they can all function as a unit, carrying out the shortening capabilities of muscle. When multiple cells with a similar function come together, it is an example of the _____
answer
tissue level
question
The small intestine contains epithelial tissue, muscle tissue, and nervous tissue. The combination of these different tissue types to form one discrete structure is an example of the _____
answer
organ level
question
The pituitary gland, adrenal gland, and other hormone-producing organs all work together to help the body send hormones through the blood stream and respond to internal changes. This is an example of the _____
answer
organ system level
question
Which of the following best represents an example at the organ level? Smooth muscle in the large intestine Hydrochloric acid Enterocytes (cells that line the small intestine) Digestive enzymes Stomach
answer
Stomach
question
The proximal convoluted tubule is a structure within the kidney nephron that plays a significant role in the reabsorption of important products that have been filtered from the blood. One of the key features of this structure is its lining. The cells that line the tubule are responsible for the transport of substances across the membrane. These cells and their collective efforts would be an example of which of the following levels? cellular level organismal level organ level molecular level tissue level
answer
tissue level
question
List the organizational levels so that they are in the correct order, ranking them from the simplest to the most complex.
answer
chemical level, cellular level, tissue level, organ level, organ system level, organismal level
question
Match each term with the correct organizational level neurotransmitters brain brain combined with the spinal cord and spinal nerves neurons nuerons and neuroglial cells
answer
brain - organ level neurons- cellular level neurotransmitters- chemical level neurons and neuroglial cells- tissue level brain combined with the spinal cord and spinal nerves
question
Match the phrases with the correct organizational level Cardiac muscle, connective tissue, and endothelial cells all collecting together to form the human heart The tibia, which is made of connective tissue and nervous tissue A thin layer of cells that collectively form the lining of the lungs to allow for the diffusion of gases Golgi apparatus, mitochondria, and other organelles compartmentalized into a single structure by phospholipids, forming a single functional unit Carbon, hydrogen, and phosphate coming together to form the phospholipids of a cellular membrane
answer
Organ level: Cardiac muscle, connective tissue, and endothelial cells all collecting together to form the human heart Organ level: The tibia, which is made of connective tissue and nervous tissue Tissue level: A thin layer of cells that collectively form the lining of the lungs to allow for the diffusion of gases Cellular level: Golgi apparatus, mitochondria, and other organelles compartmentalized into a single structure by phospholipids, forming a single functional unit Chemical level: Carbon, hydrogen, and phosphate coming together to form the phospholipids of a cellular membrane

answer
distal: superior
