Oxygen-poor blood enters the heart through the right atrium. From there blood flows through the tricuspid valve into the right ventricle. When the heart contracts during the diastolic phase, this blood is pumped out through the pulmonary arteries that run toward the lungs. At the lungs, the blood is circulated through a series of progressively smaller arterioles until it flows through capillaries lining the lungs' alveolar sacs. It is here that gas exchange takes place as oxygen is taken up by the blood, and carbon dioxide is released into the waste air.After oxygenation, the fresh blood is circulated back through the bronchial veins and into the pulmonary veins. These run from the lungs and drain into the heart's left atrium. During the systolic phase of the heartbeat, the mitral valve under the left atrium opens and permits blood to pass into the left ventricle. This chamber is heavily muscled and it has the power to pump the oxygen-rich blood out through the aorta and into the rest of the body.

Answer:
1. Scientific probe.
2. Weather station.
3. Weather station.
4. Scientific probe.
Explanation:
1. <em><u>Scientific probe</u></em>: measures a variety of data, including pH levels and conductivity. Thus, a scientific probe is a device that is typically used for measuring science-based data such as electrical conductivity, pH levels, salinity etc., of various materials.
2. <em><u>Weather station</u></em>: measures temperature, humidity, wind speed, and pressure. Basically, a weather station comprises of various devices for measuring atmospheric conditions such as thermometers, barometers, hygrometer, wind vane etc., used for the measurement of temperature, atmospheric pressure, relative humidity and wind speed respectively.
3. <em><u>Weather station</u></em>: gathers information about local atmospheric conditions.
4. <em><u>Scientific probe</u></em>: can digitally record data, such as flow rate.
