White blood cells contain many because they need to dispose of harmful intruders such as bacteria and viruses. Which of the following options correctly completes the statement above? Lysosomes Which of the following organ systems is correctly paired with its function? Endocrine/ regulation of homeostasis through hormone signaling responsible for obtaining nutrients through the breakdown and absorption of food. Digestive system responsible for transport of substance to all tissues of the body. Circulatory system primarily responsible for waste elimination. Excretory system Which of the following correctly describes anatomical position? Upright, arms at sides, palms facing anteriorly HIV is a virus that destroys the body's defense against diseases by inserting itself into the host's DNA. In which part of the infected host cell will HIV virus be found? Nucleus Osteoblasts are specialized cells that secrete the protein collagen and other substances necessary for bone formation. Which of the following organelles is more likely to be predominant in osteoblasts? Ribosomes responsible for ATP production and are considered the powerhouse of the cell. Mitochondria organelles that contain digestive enzymes. They digest excess or worn out cell parts, food, and engulfed viruses or bacteria. Lysosomes the "control center" that is responsible for directing the overall activity of the cell. The nucleus contains most of the cell's DNA nucleus two types of cell division Mitosis and meiosis is a process where a single cell divides into two identical daughter cells. The major purpose of is to replace worn-out and damaged cells. mitosis - mitosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. The purpose of is to create sex cells - sperm in males, eggs in females. Meiosis - Meiosis is the cellular process of transporting substances out of the cell. Exocytosis is the cellular process of taking substance into the cell. Endocytosis Which of the following is not located on the anterior region of the human body? Vertebral column Which of the types of tissue is responsible for providing the matrix that supports and connects other tissues of the the body? Connective tissue is responsible for transmitting nerve impulse. Nerve tissue functions as lining and covering of body surfaces and cavities. Epithelial tissue functions in facilitating voluntary and involuntary movements. Muscle tissue Which of the following is the name of the imaginary vertical plane that equally divides the body into left and right? Sagittal The is an imaginary vertical plane that divides the body into front (anterior) and back (posterior). Coronal plane The is an imaginary plane at right angle with coronal and sagittal planes and it divides the body into superior and inferior. horizontal, or transverse, plane Which of the following steps of protein synthesis occurs in the nucleus? Transcription to mRNA Which of the following describes the function of Rough Endoplasmic Reticulum? Synthesis and transport of proteins is studded with ribosomes and, as such, assists in the synthesis and transport of proteins. Rough Endoplasmic Reticulum ATP production is a function of the mitochondria while is performed by lysosomes. intracellular digestion Entry and exit of substances is facilitated by the . cell membrane Which of the following is the largest organ of the human body? Skin - A patient in a sleep clinic has a prescription for a continuous positive airway pressure machine for sleep apnea. She would like a lifetime warranty… *75 The head is to the neck. Superior means that the structure is closer to the surface of the body. Superficial indicates that the structure is located at a relatively higher position while denotes a relatively lower position. Superior, inferior [Show More]
