Across
- 3. region of the lateral horn where the temporal and occipital horns are confluent with the body of the lateral ventricle. Its primary roles are to act as a holding chamber for blood returning from the lungs and to act as a pump to transport blood to other areas of the heart
- 6. long, coiled tube that stores sperm and transports it from the testes
- 7. four cavities located within the brain that contain cerebral spinal fluid. They produce cerebrospinal fluid, and transport it around the cranial cavity
- 9. small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses electrical pulses to prompt the heart to beat at a normal rate.
- 11. stem- posterior part of the brain, continuous with the spinal cord. It controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and whether one is awake or sleepy.
- 13. blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. They are muscular tubes lined by smooth tissue and has three layers: The intima, the inner layer lined by a smooth tissue called endothelium
- 14. substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease, its products, or a synthetic substitute, treated to act as an antigen without inducing the disease
- 15. theory- currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens can lead to disease. These small organisms, too small to see without magnification, invade humans, other animals, and other living hosts.
Down
- 1. valve regulates the amount, flow direction, and pressure of cerebrospinal fluid out of the brain's ventricles. As the pressure of cerebrospinal fluid inside the brain increases, the one-way valve opens and the excessive fluid drains to the downstream cavity
- 2. a bacterium, virus, or other microorganism that can cause disease
- 4. any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
- 5. area at the back and bottom of the brain, behind the brain stem. It has several functions relating to movement and coordination and maintaining balance.
- 8. the principal and most anterior part of the brain; located in the front area of the skull and consisting of two hemispheres, left and right. It is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body.
- 10. resistance- occurs when bacteria change in response to the use of medicines
- 12. cortex- thin layer of the brain that covers the outer portion of the cerebrum. It is covered by the meninges and often referred to as gray matter.
