Anatomy
This type of muscle is under voluntary control and attached to bones.
What is skeletal muscle?
This type of macromolecule is composed of amino acids linked by peptide bonds.
What are proteins?
This organ filters blood to produce urine.
What is the endocrine system?
These significant microorganisms lack a nucleus.
What are Archaea/Bacteria?
This measurement compares systolic and diastolic pressure to assess cardiovascular health.
What is blood pressure?
This chamber of the heart pumps oxygenated blood into the aorta and systemic circulation.
What is the left ventricle?
This type of bond stabilizes protein secondary structures like alpha helices.
What is a hydrogen bond?
This branch of the autonomic nervous system is responsible for the "fight-or-flight" response.
What is the sympathetic nervous system?
This type of immune cell produces antibodies.
What are B cells?
This tool is used to produce high contrast images of soft tissues, organs, and bones.
What is magnetic resonance imaging (MRI)?
This type of connective tissue provides structural support and contains osteocytes.
What is a bone?
This molecule serves as the main electron carrier produced in glycolysis.
What is NADH?
This ion is primarily responsible for depolarization in neurons.
What is sodium (Na+)?
This staining technique differentiates bacteria into two major groups.
What is Gram staining?
A patient with low hemoglobin likely has this general condition.
What is anemia?
This valve prevents backflow from the left ventricle into the left atrium.
What is the mitral (bicupsid) valve?
This metabolic pathway produces the most ATP during aerobic respiration.
What is oxidative phosphorylation?
These microscopic structures in the lungs are the primary site of gas exchange.
What are alveoli?
This immune response is rapid and non-specific against pathogens.
What is innate immunity?
Chest pain radiating to the left arm suggests this emergency.
What is a myocardial infarction (heart attack)?
What is the median nerve?
This enzyme converts glucose-6-phosphate to fructose-6-phosphate.
What is phosphoglucose isomerase?
This structure in the nephron is responsible for most water reabsorption.
What is the proximal convoluted tubule?
These molecules present antigens to T cells.
What are major histocompatibility complex molecules (MHC)?
A patient presents with fatigue, pale skin, and shortness of breath on exertion. Lab results show low hemoglobin and small red blood cells. A deficiency of this nutrient commonly causes this type of anemia.
What is iron?
